Editing Push-up (section)

==In the animal kingdom==
There are [[zoology]] observations that certain animals emulate a ''push up'' action. Most notably various taxa of the [[Fence lizard (disambiguation)|fence lizard]] exhibit this display,<ref>Maurice Burton and Robert Burton (2002) ''International Wildlife Encyclopaedia'', published by Marshall Cavendish {{ISBN|0-7614-7272-X}}</ref> primarily involving the male engaging in postures to attract females. The [[western fence lizard]] is a particular species that also engage in this behavior.<ref>Hogan, C. Michael (2008).

Nicklas Stromberg.</ref> (It may be noted that in Mexican Spanish, push-ups are called "Lagartijas", which means "lizards".)
